Learning Objective 1: The learner will be able to understand influence of gender differences in adherence behavior in patients with hypertension

Learning Objective 2: The learner will be able to recognize the effects of illness perception on adherence of patients with hypertension in a Chinese cultural context

Purpose: The aim of this study was to examine gender differences in adherence behavior in patients with hypertension in a Chinese cultural context with respect to illness perception.

Methods:  The longitudinal and correlational design with a purposive sampling was conducted at the cardiovascular clinics of a teaching hospital in central Taiwan. A total of 123 patients completed questionnaires including Illness Perception Questionnaire-Revised and Profile of Mood States at baseline, 6 months and one year’s follow-up. Data is analyzed using  using generalized estimating equations (GEE) with STATA SE 9.0.

Results:  Male constituted 63% of the sample. Male patients is more adherent to medication recommendation than female (t=2.41, p<0.01). The factors affecting female patients' adherence to medication were age, personal control, balance causality,and the POMS score. Factors affecting male patients' adherence were age, systolic blood pressure, identity (including symptoms related to hypertension, prediction of high blood pressure), time-cyclic, emotional representations, and balance casality.

Conclusion: Our findings suggest that a gender difference in factors affecting patient adherence to medication was noted. Understanding patients’ lay views on medication adherence from a perspective of gender differences allows health professionals providing effective interventions for better adherence to therapeutic regimens.
